Gayle's former Peterborough United chairman Darragh Anthony believes the striker is a future England star.
Olly said: "Dwight is on an upward curve. It's not too bad a gamble when he's only 20 and he scored 20 goals last year.
"But I don't want to build him up too much. When Ian Wright came here from non-League he ended up playing for England and being Arsenal's top scorer. Was that a risk?
"I've earned my living taking risks so if Dwight Gayle's a risk then I'm delighted I took it."
